Die Armee ist ein zentraler Machtfaktor im Staat, militärische Informationen sind grundsätzlich gesetzlich geschützt. Das Militär bildet zudem ein soziales System mit eigenen Normen, Ritualen und Symbolen. Die hierarchische Struktur und das starke Berufsethos prägen das Militär bis heute. Innerhalb dieses Rahmens bildeten sich immer wieder geheime Netzwerke von Militärangehörigen mit abweichenden Verhaltenskodizes. Sie erregten häufig den Verdacht, gegen das eigene Militärsystem oder den Staat gerichtet zu sein. Die Autorinnen und Autoren des Bandes erkunden die Wechselwirkungen zwischen Geheimbundorganisationen, Geheimnisträgern, Verschwörern und dem Militär – von Freimaurern und Illuminaten bis zum Stauffenberg-Kreis. Das Buch enthält Beiträge in deutscher und englischer Sprache

PURPOSE To evaluate image contrast and color setting on assessment of retinal structures and morphology in spectral-domain optical coherence tomography. METHODS Two hundred and forty-eight Spectralis spectral-domain optical coherence tomography B-scans of 62 patients were analyzed by 4 readers. B-scans were extracted in 4 settings: W + N = white background with black image at normal contrast 9; W + H = white background with black image at maximum contrast 16; B + N = black background with white image at normal contrast 12; B + H = black background with white image at maximum contrast 16. Readers analyzed the images to identify morphologic features. Interreader correlation was calculated. Differences between Fleiss-kappa correlation coefficients were examined using bootstrap method. Any setting with significantly higher correlation coefficient was deemed superior for evaluating specific features. RESULTS Correlation coefficients differed among settings. No single setting was superior for all respective spectral-domain optical coherence tomography parameters (P = 0.3773). Some variables showed no differences among settings. Hard exudates and subretinal fluid were best seen with B + H (κ = 0.46, P = 0.0237 and κ = 0.78, P = 0.002). Microaneurysms were best seen with W + N (κ = 0.56, P = 0.025). Vitreomacular interface, enhanced transmission signal, and epiretinal membrane were best identified using all color/contrast settings together (κ = 0.44, P = 0.042, κ = 0.57, P = 0.01, and κ = 0.62, P ≤ 0.0001). CONCLUSION Contrast and background affect the evaluation of retinal structures on spectral-domain optical coherence tomography images. No single setting was superior for all features, though certain changes were best seen with specific settings.
